METHOD FOR PREDICTING THE ONE-YEAR RISK OF ADVERSE CARDIOVASCULAR EVENTS IN MEN AFTER DECOMPENSATION OF CHRONIC HEART FAILURE WITH PRESERVED LEFT VENTRICULAR EJECTION FRACTION AND OBSTRUCTIVE SLEEP APNEA SYNDROME Russian patent published in 2022 - IPC G01N33/50 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used in cardiology, functional diagnostics, therapy, pulmonology. In patients, the level of sST2 in the blood serum, the apnea / hypopnea index and the left ventricular myocardial mass index are determined, and the likelihood of developing unfavorable cardiovascular events is determined by the formula and with a P value equal to or more than 0.65, the risk of developing unfavorable cardiovascular events as high, and with a value of P less than 0.65, the risk is assessed as low.

EFFECT: method allows to increase the accuracy of the prediction of the onset of unfavorable cardiovascular events: progression of CHF with the transition to a more severe functional class of CHF according to NYHA, hospitalization for cardiovascular diseases, development of paroxysms of atrial fibrillation or registration of high-grade ventricular rhythm disturbances - III-V class according to Ryan, death in patients with chronic heart failure with preserved ejection fraction and obstructive sleep apnea syndrome within one year of follow-up after heart failure decompensation.
